About Bosu

A BOSU Balance Trainer is a fitness training device, invented in 2000 by David Weck, consisting of an inflated rubber hemisphere attached to a rigid platform. The device is often used for balance training. When the dome side faces up, the BOSU ball provides an unstable surface while the device remains stable. This combination of stable/unstable allows a wide range of users.With the dome side up, the device can be used for athletic drills and aerobic activities. The device can be flipped over so that the platform faces up. In this position, the device is highly unstable and can be used for other forms of exercise.
The name initially came from an acronym standing for "Both Sides Up" - a reference to the two ways a BOSU ball can be positioned. The acronym has now evolved to a new meaning "Both Sides Utilized".
